Venezuelan President Nicolás Maduro is currently amassing armed forces along the border with Guyana following a controversial referendum to annex 74% of the country's land area, greatly complicating the long term positions of ExxonMobil and Chevron in the region.
Sunday's referendum to annex Guayana Esequiba (Essequibo in English), a sparsely-populated territory home to and the vast majority of Guyana's only recently exploited oil resources, passed with 90% support from Venezuelan voters, according to government sources.
